Application filed December 28, 1920. Serial Ito. 438,739.

To whom it may concern:

Be it known that I, CYRILDE Vnma, manufacturer,-citizen of the Republic of France,

residing at 4 Rue Carpeaux, Paris, France, 5 have invented certain new and useful Improvements in or Relating to Phonographs' (for which I have filed application for patent in England, provisional application dated July 15, 1919, and complete application dated February 6, 1920, #17704/19),

of which the following is a specification.

This invention relates to improvements in magazine phonographs of the type comprising a set of vertically superposed carriers,

each adapted to hold a disc record, which are arranged so that any selected carrier can be brought into such a position that vertical displacement of a turntable will cause the record held by the selected carrier to en- 20 gage with the said turntable, so that the record may be rotated thereby and played- A magazine phonograph of the above type has been proposed in which the bringing into position of the selected record readybfor a vertical displacement of all the carriers so as to bring the carrier holdin the selected record to a definite height, followed by a horizontal displacement of the said selected carrier at the said definite height into a position immediately above the turntable, the subsequent vertical displacement of the turntable being of limited extent.

It has also been proposed that after the selection of the record, the binding into position of the selected record and the play ing of the same should be effected automatically by the movement of one handle only. But the arrangement is such that the selected record is placed into position-and started before the complete winding up of the spring. This is liable to lead to insufficient winding.

The present invention consists in an imaa proved magazine phonograph of the type first above referred to, in which the bringing into position of the selected record ready for engagement by the turntable is efiected by a solely horizontal displacement of. the

1 carrier holding the selected record, the sub sequent vertical displacement of the turntable being substantially equal to the height of the set of superposed carriers.

The following description relates to a magazine phonograph worked directly by means of a crank handle.

The playing of the selected record contained inthe magazine is eifected simply by the two following operations (1) The pointer of the selecting mechanism is moved. opposite a number correspondin to the said record in a listfixed on the outside of the apparatus.

(2) The crank handle is turned a certain number of times, according to the instructions, in the direction of an arrow.

The magazine phonograph comprises in compact arrangement A magazine for disc records; A selecting mechanism for selecting the disc;

A rack bar for conveying the selected disc out'of themagazine;

A first spring motor mechanism for imparting to the disc-the rotary motion necessary for playing the record thereon;

A second spring motor mechanism for raising the first spring motormechanism, and the selected disc so as to bring the latter into contact with the sound-box;

Various automatic mechanisms for actuatin all these devices, and

arious safety devices for preventing the apparatus from being damaged.

This invention will now be described more fully with reference to the accompanying drawings wherein l is a perspective View of the whole apparatus showing the selecting mechanism with its safety devices, and the main parts for actuating the turntable, the upper disc having been brought above the turntable.

The construction and operation of the mechanism for selecting the desired record are hereinafter described:

The whole apparatus is contained within, a casing the front and rear walls of which are desi ated by C and D (Fig. 1), the side wal s E and F not being shown in said figure. Each record disc is placed on a disc carrier A, provided at its central part with an opening B, the diameter of which is smaller than the diameter of the record so that the latter rests on the carrier only by its peripheral part. The carriers may slide' inside grooves 108 diametrically opposed, so that the disc may come exactl above the turntable and may be raised during the upward vertical movement of the latter.- In order to select the referred disc, the pointer 129 (Fig. 1) whic is situated on the out side and which is designed to be moved upon the dial 121 to a number corresponding to the selected record, is mounted on a shaft I (Fig. 1 and Fi 7) which imparts rotation to the vertical 3 aft 2 through bevel pinions 3 and 4. On the shaft 2 there are mounted horizontal rods 5 with upturned ends so arranged that when the pointer has been move opposlte a number, the corresponding rod will push the hook 6 of the selected disccarr er-ias shown in Fig. 2. A rod 7 fixed vertically the rack bar 8 is then able to move the disc. During the beginning of the translation of the disc-carrier, the hook 6 leaves the rod 5, but then comes into contact with the bottom of the groove 108 (Figs. 4 and 8) inside which the carrier slides, and is thus maintained in engagement with the rod 7 driving the disc-carrier. The hooks 6 of the other discs are held back by their,

springs 6 (Figs. 4 and 5).

Fig. 8 shows that the rack bar is provided over its whole length with lateral flanges 8 sliding inside two fixed U-shaped pieces 8".

This selecting mechanism comprises also a safety device operating as follows If tworods 5 should be in contact withv spring 12 (Fig. 7).

When the apparatus is working, another safety device consists of a spring controlled lever 13 (Figs. 1, 4 to 7) whose blocking position is shown in Fig. 4:, in which the end above the rack bar is shown in dotted lines as it permits this blocking. When the apparatus is in the position shown in Fig. 5, the end of the rack bar.8 pushes back the pointed projection 14 of lever 13 and maintains the left hand end of the latter out of engagement with the lever 9, but when the rack bar has been moved to the left (Figs. 1, 5 and 6), thev spring 13 brings the lever 13 in the position shown in said figures, and the left hand end of said lever prevents the lever 9 from pivoting.

The starting of the apparatus by means of a suitable number of revolutions of the driving crank is efiected in the manner hereinafter described with reference to Figs. 6, 7 and 8.

The shaft 18 on which the driving crank 19 is fixed, drives the oblique shaft 29 by means of two bevel pinions 30 and 31. The shaft 29 drives the shaft 32 through a worm 33 and its worm wheel 34. The shaft 32 is connected to the spring of the spring motor mechanism 63 (Fig. 15) hereinafter mentioned, for lifting and lowering the spring motor 64 and the turntable 82. Since this spring motor makes one revolution during a complete operation of the apparatus, the pinions are so arranged that the shaft 32 will make only one revolution for instance for eight revolutions of the crank. The shaft 32 also drives the shaft 25 (Figs. 1 and 15) by the intermediary of two spur pinions 36 and 37. On this shaft 25 is fixed int the toothed wheel 38 engaging with the rack 1 bar 8. While rotating, this toothed wheel brings the rack bar into the position shown in Figs. 1, 6 and 7. The said toothed wheel 38 is cut in the part ofits circumference corresponding to the position of the rack bar shown in said Fig. 7. The rod 7 fixed on the saidbar .brings the selected disc exactly over the disc-carrier in such a manner the angle iron 40.

and 43, 44, is suitably esca ees engaged by the latter and brought into '85 connected to the sound-box. The rod 7 is guided in its movements by the nib 39 and The rack bar at the endof its travel is held by a pointed projection constituted by the end of a lever 41 which engages in a corresponding notch 41" (Fig. 6).

The shaft 29 drives the shaft 42 through two bevel pinions 43 and 44. This shaft 42 serves to wind the spring of the spring motor 64 that produces the rotation of the discs. The pinion 43 is not fixed on the shaft 29 but 1S pressed'by a spring 45 against a fibre disc 46 (Fig. 7) fixed on a plate 47 keyed on the shaft 29, so that when said spring has been completely Wound, the pinion 43 will remain stationary andthe plate will slip. The assembly of pinions 30, 31 multipled in order to afi'ord the complete winding of the spring motor 64 by means of the eight turns of the crank 19.

In order to avoid the risk of turning the crank in the wrong direction, its shaft 18 carries a ratchet wheel 49 engaged by a spring pawl 48 (Fig. 7)-

The toothed wheel 38 engaging with the rack carries a-pin 50 (Figs. 9, 10 and 11) which, after having moved the rod 51 into the position shown in Fig. 9, releases it when the rack has completed its outward movement; the rod 51 is then moved back by its spring 52 together with the rocking arm 53 on which it is fixed. This rod 51. is stopped in the position shown in Fig. 10 by the stud- -.consequently the arm 56 and has not dropped owing to the spring 61' a through the medium of the 54 (Figs. 9, 10 and 15) the latter being actuated as it will be seen hereinafter, but in this return movement the first tooth 53 of the lever 53 has lifted the roller 55 and Figs. 10, 11 and 15) to which it is connecte by means of the lever 57 mounted on said arm 56 by means of the axle pin 100' and may rock to the right but not to the left. The arm 56 is fixed to a shaft 58 whose other end carries an arm 56 recalled by the spring 56". The pin 59 fixed to the fiat member 62 slidable on arm 56 has moved out of the notch of the wheel 60 in the raising of the arm 56 (Fig. 12) which has moved it back together with the part 62 on which it is fixed, the said part 62 being.slidably'attachedto the arm 56 as shown in the drawings (Fig. 12). The wheel 60 fixed to the spring motor 63 (Figs. 12 and 15) being thus released begins to turn and to lift the spring motor 64 as well as the turntable for the disc record crank 65 secured to the wheel 60; the pin 65 .is coupled by a connecting rod 66 to an arm.

66 on the lever 67 which also rises and carries up the spring motor 64 by the interpin 65 on a naediary of the roller 67*. The spring motor 64 is balanced by a counterweight 68 fixed to the other end of the, lever 67 which is fulcrumed on the axle 69. This spring motor is guided in its rise by two tubes 70 and 71 ig. 14) fixed on a cross member 72 and adapted to slide along vertical rods 73 and 74.

When the wheel 60 has made half a revolution, the pin 59 drops into the second notch and since the stoppage is not instantaneous, the part 62 is pulled, and the spring 61 is tensioned again. In order to avoid the stoppages causing too great strains upon the wheel 60 and the part 62, the arm 56 and the axle 58, a brake shoe 75 (Figs. 10 and 11) mounted on a rod fixed to the axle 58 exerts a braking action, each time the pin 59 enters one of the notches of the wheel 60, upon a wheel 76 actuated by the springmotor 63 by means of the wheel 125 and the worm 126 (Fi 11).

T e spring motor 64 has been wound in the shaft 42 through the medium of two unlversal joints 77 and 87 (Figs. 1 and 14) of an extensible shaft 79 and two pinions 80 and 81.

The disc-carrier plate or turntable 82 (Figs. 12, 13 and 14) is braked when it is in its lower position, by a brake shoe 83; but immediately it rises, it loses contact wlth the said brake-shoe, and resumes its rotational motion. In rising it meets the disc 84 which has been brought in its carrier above it by the rack bar as above described, and it raises the disc which comes into contact just before its point of maximum ascent, with the needle 85 of thesound box. The latter is maintained exactly at the/necessary place by a stud 86 engaging in the notch 87 Fig. 14). This stud serves as a guide .to the Sound-box and compels its needle to engage in a thread of the disc and thus prevent the derailing which takes lace sometimes in the ordinary apparatus. he sound-arm 111 is mounted on a pivot 88 and is connected either to a horn or to one or more acoustic tubes.

On the vertical shaft 82 of the disc-car rod 97 thus causing the rocking of the lever 98 on which the tappet 54 is situated.

The latter is thus moved towards the rear and the lever 53 (Figs. 10 and 11) thus released rochs anew toward the left,

strikes the tappet 99. In this movement the second tooth 53 of the said lever raises again the roller 55, like the first time, this movement having for effect to release the wheel 60 which makes a further half revolution and returns the sprin motor 64 with the turntable into the position shown in Fig. 12, by means of the crank 65', connecting rod 66, arm 66 and lever 67. During the descent, the disc is deposited upon its carrier.

When the crank handle 19 is turned afresh for a next operation of the apparatus, the pin 50 moves the rod 51 and the arm 53 again into the position shown in Fig. 9. During this movement the teeth of the arm 53 cause the support 57 of the roller 55 (Fig. 10) to rock to the right on its axle 100, and the latter returns by gravity into the position shown in Fig. 9, without the lever 56 being raised.

When the spring motor 64 of the disc carrier plate has returned. into its lower position, the return of the disc on its carrier into the magazine is effected in the following manner The tube 70 which is fixed to the spring motor 64 by means of the bar 72 (Figs. 1 and 14) and guides the upward movement of sprin motor 64 and turntable 82 as abovesai carries a stop 101 which in descending, brings through the medium of the tappet 102 the lever' 103 into the position shown in. Figs. 1 and 7. When the spring motor 64 has almost reached the bottom, the ta pet 102 escaping from the stop 101 allows t e lever 103 to be moved rapidly backwards by the spring 104. Its end comrising an inclined pusher 103 as shown in ig. 6 causes the lever 41 to rock on its axle 41*by means of the stop 105 which is pushed towards the rack-bar and this has the effect of releasing the rack bar 8 that was being held by the nose of the lever 41 engaged inside the notch 41". The rack bar is then returned to its initial sition by the action of the spring 106 w ich pulls the rod 7 that is fixed on it without drivin back the wheel 38, as the rack bar is o posite the cut away portion of said wheel. 11 this manner the disc which has been played, is returned to the magazine.

In order that the return movement shall not be too abrupt the rack bar actuates either a. fly 107 or any suitable braking device. For the purpose of deadening the shock at the end of the course, the grooves 108 (Fig. 12) in which the disc-carriers slide have rubber stops 109 at their ends.

During the ascent of the spring motor, the stop 101 (Fig. 7) raises the tappet 102 which rocks on its axle without actuating the lever 103 and is brought back by the spring 102". 7

When the spring motor 64 (Fig. 12)

moves down again, the sound arm 85 is stopped by the inclined surface 110 alon which it slides until the stud 86 drops bacl i into the notch 87.

The eration of the phonograph may be reca itu ated as follows First, a record disc is selected by rotating the shaft 1 in order to bring the'index 120 opposite the corresponding member of the dial 121. This brings the corresponding arm into contact with the hook 6 of the desired disc-carrier and engages said hook lwith the vertical rod 7 secured on the rack ar 8. By rotatin the crank 19, and thereby the toothed whefi 38 engaging the rack bar 8,

said rack bar is translated horizontally with the rod 7 and the selected disc-carriage. By this movement the disc is brought above the turntable 82, and meanwhile the disc selecting device is blocked by means of the lever 13 moved by its spring 13 and engaging with the lever 9.

Moreover, when the movement of the rack bar is over the nose piece of the lever 41 engages the corresponding notch 41 of the rack bar. (Y

During the rotation of the crank 19, the shaft 29 has been rotated also by the inter- 'mediary of the pinions 30 and 31, and the shaft 29 drives the shaft 32 throu h the worm 33 and the worm wheel 34, and %y this movement the spring of the spring motor 63 is wound up.

During the rotation of the toothed wheel 38, the stud pushes the pivoting arm 53 to the right (Fig. 8) and releases the same when the rack bar has completed its movement. The arm 53 is then returned to the left by the spring 52 and the tooth 53 raises the plvoting arm 56 by the intermediary of the roller 55. The stud 59 is thus disengaged from the notch of the wheel 60 which begins to rotate under the driving action of its spiral spring. The crank rotates with the wheel 60, and the turntable 82 and its sprin motor 64 are lifted by the intermediary o the connecting rod 66. At the same time, the shaft 29 actuates'the pinions 43, 44, the shafts 42 and 79, the pinions and 81 and thereby winds up the spring motor 64 of the turntable 82 which begins to turn slowly until it is out of contact with th brake shoe 83.

On its way up, the turntable passes through the disc carriage, raises the record all newest During the reproduction of the disc the cam wheel has made one revolution, so that when the reproduction is over the cam pushes the pivoting lever 92 which actuates the rods 93, 94, 95, 97, the latter actuating the tappet 54 which releases the arm 53 returned towards the left (Figs. 10 and 11) by the sprin 52. The second tooth 53 raises again t e arm 56. releases again the wheel and causes the descent of the turntable 82 with the record disc by means of the crank and connecting rod 66.

It results from the above description that during the descent of the turntable 1. The record disc is laid upon its carriage.

2. The rocking arm 102 is pushed down and then suddenly released and returned by the spring 104:, thus causing the lever 103 to strike on the pivoting lever 41 and to disengage its nose from the rack bar 8 which may be moved backwards to its initial position by the spring 106. By the return movement of the rack bar the record disc and its carriage are broughtback into the ma azine, this movement being braked by the y 107.

3. The end of the descent of the turntable and its rotation are braked by the brake shoe 83.

d. The sound arm slides along the inclined ridge 110 and is brought back to its initial position, corresponding to the beginning of the reproduction of a record disc, the stud 86 dropping back into the fixed notch 87.

The phonograph is now ready for a followin operation.
